摘 要
随着电子系技术的发展，以ARM微处理器为核心的电子应用系统已经进入人们日常生产生活的各个方面，ARM以其出色的性能优势赢得了广大电子产品开发者的认可。本文作者根据自己的课程学习，掌握了 ARM系统微处理器相关的基础知识和基本技术，而这些技术需要实地的实验设计来帮助巩固和深入。本案例属于日常生活当中和学习研究中比较常见和熟悉的应用，不但有比较强的综合性，而且有很高的趣味性。
在我们系统学习了嵌入式系统开发与应用实践课程之后，结合对ARM微处理器的基础知识和基本技术的掌握，实现了简单电子词典设计。本设计主要解决了基于S3C44B0X 通过I/O控制发光二极管的电子词典。

ABSTRACT
Along with the electronic technology development, with ARM microprocessor as the core of the electronic application system has entered people's daily production in all aspects of life, ARM with its excellent performance advantages to win the majority of electronic product developers recognized. In this paper the authors according to their course of study, master of the ARM system related to the basic knowledge and technology, and these technologies require field experiments designed to help consolidate and development. This case belongs to the daily life and study in the more common and familiar with the application, not only have strong comprehensive, but also have high interest.
In our system, learning embedded system development and application practice of course, according to the ARM microprocessor basic knowledge and basic technical mastery, the realization of a simple directory design. The design of the main solution based on S3C44B0X through I / O control led flashing.
Key words: ARM microprocessor; directory; S3C44B0X
